MCP2515
Stand-Alone CAN Controller with SPI Interface
Features:
? Implements CAN V2.0B at 1 Mb/s:
- 0 – 8 byte length in the data field
- Standard and extended data and remote
frames
? Receive Buffers, Masks and Filters:
- Two receive buffers with prioritized message
storage
- Six 29-bit filters
- Two 29-bit masks
Description
Microchip Technology’s MCP2515 is a stand-alone
Controller Area Network (CAN) controller that
implements the CAN specification, version 2.0B. It is
capable of transmitting and receiving both standard
and extended data and remote frames. The MCP2515
has two acceptance masks and six acceptance filters
that are used to filter out unwanted messages, thereby
reducing the host MCU’s overhead. The MCP2515
interfaces with microcontrollers (MCUs) via an industry
standard Serial Peripheral Interface (SPI).
? Data Byte Filtering on the First Two Data Bytes
(applies to standard data frames)
? Three Transmit Buffers with Prioritization and

Abort Features
? High-Speed SPI Interface (10 MHz):
- SPI modes 0 , 0 and 1 , 1
? One-Shot mode Ensures Message Transmission
is Attempted Only One Time
? Clock Out Pin with Programmable Prescaler:
- Can be used as a clock source for other
device(s)
? Start-of-Frame (SOF) Signal is Available for
Monitoring the SOF Signal:
- Can be used for time-slot-based protocols
and/or bus diagnostics to detect early bus
degradation
? Interrupt Output Pin with Selectable Enables
? Buffer Full Output Pins Configurable as:
- Interrupt output for each receive buffer
- General purpose output
